African Teak Wood(Tectona grandis)
Plantation And Naturally Grown Teak. Heartwood tends to be a golden or medium brown, with color darkening with age. Teak has been considered by many to be the gold standard for decay resistance, and its heartwood is rated as very durable. Teak is also resistant to termites, though it is only moderately resistant to marine borers and powder post beetles. Easy to work in nearly all regards, with the only caveat being that Teak contains a high level of silica (up to 1.4%) which has a pronounced blunting effect on cutting edges.. This Specie Can be produced and shipped in Saw logs, Peeled Logs, Square edged timber, Round edged timber, Flooring boards, Finishing boards, Unedged boards, Square logs, Decking boards, Parquet floors, Floor planks, Wall coverings(Veneers Sheets), Plywood, Roof coverings, Rattan, Sleepers, Polls and proprietary grade hardwood products of both finish and unfinished.

ALL ABOUT TEAK WOOD
- Color/Appearance: - Heartwood tends to be a golden or medium brown, with color darkening with age.
- Grain/Texture: - Grain is straight, though it can occasionally be wavy or interlocked. Coarse, uneven texture and moderate to low natural luster. Raw, unfinished wood surfaces have a slightly oily or greasy feel due to natural oils.
- Endgrain: - Ring-porous or semi-ring-porous; large to very large solitary earlywood pores, medium to large latewood pores, few; solitary and in radial multiples of 2-3; tyloses and other heartwood deposits (light-colored) common; medium rays visible without lens, spacing normal; parenchyma vasicentric, and banded (marginal), with bands sometimes wide enough to enclose entire earlywood pores.
- Rot Resistance: - Teak has been considered by many to be the gold standard for decay resistance, and its heartwood is rated as very durable. Teak is also resistant to termites, though it is only moderately resistant to marine borers and powder post beetles.
- Workability: - Easy to work in nearly all regards, with the only caveat being that Teak contains a high level of silica (up to 1.4%) which has a pronounced blunting effect on cutting edges. Despite its natural oils, Teak usually glues and finishes well, though in some instances it may be necessary to wipe the surface of the wood with a solvent prior to gluing/finishing to reduce the natural oils on the surface of the wood.
- Odor: - Teak can have a leather-like scent when freshly milled.
- Allergies/Toxicity: - Although severe reactions are quite uncommon, Teak has been reported as a sensitizer. Usually most common reactions simply include eye, skin, and respiratory irritation, as well as other health effects, such as pink eye, rash, nausea, asthma-like symptoms, and vision effects. See the articles Wood Allergies and Toxicity and Wood Safety for more information.
- Pricing/Availability: - Despite its widespread cultivation on plantations worldwide, Teak is very expensive. It is perhaps one of the most expensive lumbers on the market, at least for large-sized, non-figured wood. Other woods are more expensive, but are typically only available in small pieces, (i.e., African Ebony or Snakewood), or they are valued solely for the figure of their grain (i.e., burl woods, Pommele Sapele, or Waterfall Bubinga).
- Sustainability: - This wood species is not listed in the CITES Appendices or on the IUCN Red List of Threatened Species.
- Common Uses: - Ship and boatbuilding, veneer, furniture, exterior construction, carving, turnings, and other small wood objects.
- Comments: - Sometimes called Burmese Teak, this name is used to differentiate natural-grown trees (typically from Myanmar, aka Burma) from Teak grown on plantations. Used extensively in India and within its natural range for centuries, Teak has grown into a worldwide favorite. With its superb stability, good strength properties, easy workability—and most of all, its outstanding resistance to decay and rot—it’s no wonder that Teak ranks among the most desired lumbers in the world.
